There is a number next to there name (100,99,98 ect) that is there rating. But there are some great vendors that are not 100 do to some idiot buyers. So it is better to click on the vendors page and at the bottom read his reviews left buy his buyers. Read a lot of them to get a fill. It will tell you how old they are and so forth. Also on the vendors items for sale there is feedback at the bottom that is item specific. Read that and you can see what is said about the item you want. With both of those you can get a good feel for a vendor. Also helps to ALWAYS read the vendors page. Any good vendor will update it with info about him that could delay them from shipping out or what hours they are online to actually return messages. Hope that helps And WELCOME! Just spend some time looking around. You wil catch on fast.
